Novel styryl dyes containing dithia-15(18)-crown-6(5)-ether moieties were synthesized. Their selective complex formation with Hg2+ and Ag+ ions was studied by (0)1H NMR and electronic spectroscopy; the stability constants of the Ag+ complexes and the relative stability constants (in relation to benzodithia-18-crown-6) of the Hg2+ complexes were determined. The chemical shifts of the beta,beta'-protons in the CH2S group change upon the complex formation in parallel with the logK(1) values of the complexes.
